More Like Writing Than Calculation

In terms of niche markets I wish to operate in the philosophy of computing taken from a classical approach.  Ancient computing is presently associated only with calculation tools.  Our own modern experience has demonstrated that general purpose computing exists that has very little to do with mathematical calculations.  On the macro level there is a host of high-level applications and programming interfaces; on the micro level, we must substantially extend the notion of "mathematical" if we are to include (..).  I would like to posit that apart from shared foundations in mathematical logic, and the hysteresis of their original design purposes, modern electronic computing technology has more in common with writing than it does with numerical calculation.  When viewed in this manner, it is much easier to draw connections between ancient and modern computing activities.
